In Ohio, instructor Robert Balla faces a new cap on the number of hours he can teach at Stark State College. In a Dec. 6 letter, the North Canton school told him that “in order to avoid penalties under the Affordable Care Act… employees with part-time or adjunct status will not be assigned more than an average of 29 hours per week.”

Mr. Balla, a 41-year-old father of two, had taught seven English composition classes last semester, split between Stark State and two other area schools. This semester, his course load at Stark State is down to one instead of two as a result of the school’s new limit on hours, cutting his salary by about a total of $2,000.

Stark State’s move came as a blow to Mr. Balla, who said he earns about $40,000 a year and cannot afford health insurance.

“I think it goes against the spirit of the [health-care] law,” Mr. Balla said. “In education, we’re working for the public good, we are public employees at a public institution; we should be the first ones to uphold the law, to set the example.”
